This paper presents a new simple and straightforward method for designing Self-Testing Embedded (STE) parity checkers. The building block is the two-input XOR gate. During normal, fault-free operation, each XOR gate receives all possible input vectors. The great advantage of the proposed method is that it is the only one that gives, in a simple and straightforward way, optimal STE realizations ...

In this paper, a new design of three transistor XOR gate is proposed using Independent Driven Double Gate MOSFET to achieve ultra-low power in sub threshold conduction. The proposed design has been compared with the three transistor XOR implemented using Symmetrical Driven Double Gate MOSFET in sub threshold region. A three transistor XOR gate designed using Independent Driven Double Gate MOSFE...

Quantum-dot cellular automaton (QCA) is a novel nanotechnology with a very different computational method in compared with CMOS, whereas placement of electrons in cells indicates digital information. This nanotechnology with specifications such as fast speed, high parallel processing, small area, low power consumption and higher switching frequency becomes a promising candidate for CMOS tec...

This work demonstrates two DNA-based logic circuits that behave as a half-adder and a half-subtractor. A half-adder is composed of an AND gate and an XOR gate, whereas a half-subtractor consists of an INH gate and an XOR gate. The proposed designs are inspired by molecular beacons.

In this paper a new architecture for delay locked loops will be presented.  One of problems in phase-frequency detectors (PFD) is static phase offset or reset path delay. The proposed structure decreases the jitter resulted from PFD by switching two PFDs. In this new architecture, a conventional PFD is used before locking of DLL to decrease the amount of phase difference between input and outpu...

Quantum dot Cellular Automata (QCA) is one of the important nano-level technologies for implementation of both combinational and sequential systems. QCA have the potential to achieve low power dissipation and operate high speed at THZ frequencies. However large probability of occurrence fabrication defects in QCA, is a fundamental challenge to use this emerging technology. Because of these vari...

The dynamics of a generic quantum XOR gate operation involving two interacting qubits being coupled to a bath of quantum harmonic oscillators is explored. By use of the formally exact quasiadiabatic-propagator path-integral methodology we study the time-resolved evolution of this interacting and decohering two-qubit system in presence of time-dependent external fields. The quality of the XOR ga...

A hybrid network is proposed in dynamic CMOS XOR/XNOR gate to avoid signal skew and reduce the power consumption. Compared to the standard N type dynamic gate leakage power, dynamic power and layout area of the novel XOR/XNOR gate are reduced. In this paper we studied different technologies, their merits and demerits. Comparison of different technologies is completely on the basis of leakage po...
